From 2007-2009 the Terwillegar Park Concept Plan Study took place. The study built on the 2005 document "A Vision for Terwillegar Park".
The purpose of the Study was to develop an overall concept plan, management objectives and development guidelines for the next ten years.
Public consultation with a stakeholder advisory committee, park users and the general public took place throughout the concept planning phase of the project.
In January 2009, the Terwillegar Park Concept Plan Study was approved by City Council.
